Abstract

A storage control device of an outboard motor writing operation history information of the outboard motor to a nonvolatile memory by using an electric power generated by driving of an internal combustion engine, the storage control device includes a stop instruction detecting unit detecting a stop instruction of the driving of the internal combustion engine by a boat operator, a writing unit writing the operation history information to the nonvolatile memory in accordance with the stop instruction detected by the stop instruction detecting unit, a write judgment unit judging whether or not the operation history information is written to the nonvolatile memory by the writing unit, and a stop processing unit stopping the driving of the internal combustion engine after it is judged that the operation history information is written to the nonvolatile memory by the write judgment unit.

Claims

1. A storage control device of a batteryless outboard motor writing operation history information of the batteryless outboard motor which does not include a battery and operates by using only electric power generated by driving of an internal combustion engine to a nonvolatile memory, the storage control device comprising:

a stop instruction detecting unit detecting a stop instruction of the driving of the internal combustion engine by a boat operator;

a writing unit writing the operation history information to the nonvolatile memory in accordance with the stop instruction detected by the stop instruction detecting unit before the driving of the internal combustion engine is stopped;

a write judgment unit judging whether or not writing the operation history information to the nonvolatile memory by the writing unit is completed; and

a stop processing unit stopping the driving of the internal combustion engine based on the stop instruction detected by the stop instruction detecting unit,

wherein the stop processing unit continues the driving of the internal combustion engine for a period of time between when the stop instruction is detected by the stop instruction detecting unit and completion of the writing the operation history information to the nonvolatile memory by the writing unit is judged by the write judgment unit and after that, stops the driving of the internal combustion engine.

2. The storage control device according to claim 1, further comprising:

a storage processing unit storing the operation history information of the batteryless outboard motor at a volatile memory,

wherein the writing unit writes the operation history information stored at the volatile memory by the storage processing unit to the nonvolatile memory.

4. The storage control device according to claim 2, wherein the write judgment unit judges whether or not a process writing the operation history information to the nonvolatile memory is finished by judging whether or not the operation history information written to a volatile memory is identical with the operation history information written to the nonvolatile memory.

3. A storage control method of a batteryless outboard motor writing operation history information of the batteryless outboard motor which does not include a battery and operates by using only electric power generated by driving of an internal combustion engine to a nonvolatile memory, the storage control method comprising:

a stop instruction detecting step of detecting a stop instruction of the driving of the internal combustion engine by a boat operator;

a writing step of writing the operation history information to the nonvolatile memory in accordance with the stop instruction detected by the stop instruction detecting step before stopping the driving of the internal combustion engine;

a write judgment step of judging whether or not writing the operation history information to the nonvolatile memory is completed by the writing step;

a stop processing step of stopping the driving of the internal combustion engine based on the stop instruction detected by the stop instruction detecting step; and

continuing driving the internal combustion engine for a period of time between the detection of the stop instruction and completion of the writing of the operation history information to the nonvolatile memory from the writing step, and after that, stopping the driving of the internal combustion engine.

5. A batteryless outboard motor, comprising:

a storage control device writing operation history information of the batteryless outboard motor which does not include a battery and operates by using only an electric power generated by driving of an internal combustion engine to a nonvolatile memory,

wherein the storage control device includes;

a stop instruction detecting unit detecting a stop instruction of the driving of the internal combustion engine by a boat operator;

a writing unit writing the operation history information to the nonvolatile memory in accordance with the stop instruction detected by the stop instruction detecting unit before the driving of the internal combustion engine is stopped;

a write judgment unit judging whether or not the operation history information is written to the nonvolatile memory by the writing unit; and

a stop processing unit stopping the driving of the internal combustion engine based on the stop instruction detected by the stop instruction detecting unit,

wherein the stop processing unit continues the driving of the internal combustion engine in a period of time between the stop instruction is detected by the stop instruction detecting unit and finish of writing the operation history information to the nonvolatile memory by the writing unit is judged by the write judgment unit, and after that, stops the driving of the internal combustion engine,

wherein an engine rotation speed of the internal combustion engine is the same at a time before the stop instruction is detected by the stop instruction detecting unit and in the period of time between the stop instruction is detected by the stop instruction detecting unit and the writing the operation history information to the nonvolatile memory by the writing unit is finished, and

the engine rotation speed is gradually lowered and then stopped after the writing the operation history information to the nonvolatile memory by the writing unit is finished.
